An innovative approach for dynamic key dependent S-Box to enhance security of IoT systems
Measurement: Sensors, 2023 The Internet of Things (IoT) foresees pervasive and connected smart nodes that interact independently while offering varied services. Today, IoT nodes are a treasure house of data and hence security has become a major concern in IoT networks ...

Throwing Boomerangs into Feistel Structures
IACR Transactions on Symmetric Cryptology, 2022 Automatic tools to search for boomerang distinguishers have seen significant advances over the past few years. However, most previous work has focused on ciphers based on a Substitution Permutation Network (SPN), while analyzing the Feistel structure is

Journal of Advances in Modeling Earth Systems, Volume 15, Issue 10, October 2023., 2023 Abstract We address the question of how to use a machine learned (ML) parameterization in a general circulation model (GCM), and assess its performance both computationally and physically. We take one particular ML parameterization (Guillaumin & Zanna, 2021, https://doi.org/10.1002/essoar.10506419.1) and evaluate the online performance in a different ...

IET Image Processing, Volume 17, Issue 10, Page 2984-3001, 21 August 2023., 2023 In IoT sensors, which are used to record and send images, secure image transmission is of great importance. Therefore, we need to use encryption, watermarking and compression processes. Here, a new integrated method of lightweight encryption, watermarking and compression for the fast and secure transmission of images is proposed.

Differential analysis of the NBC algorithm based on mixed integer linear programming model
SECURITY AND PRIVACY, Volume 6, Issue 4, July/August 2023., 2023 Abstract This paper mainly studies mixed integer linear programming (MILP)‐based cryptanalysis on round‐reduced NBC algorithm with generalized Feistel structure. First, each component of the algorithm is equivalently described by linear inequality equations, and the propagation rules of differential characteristics and linear approximation are ...

Multiset Structural Attack on Generalized Feistel Networks [PDF]
Mathematical Problems in Engineering, 2019 In this paper, we present new generic multiset attacks against generalized Feistel networks, by which we can recover all the unknown round functions completely instead of deciding whether an unknown encryption oracle is such network or a random permutation.
